“…We have, therefore, chosen two glassy polymers, Polysulfone (PSf), and Poly(furfuryl) alcohol (PFA) as the membrane materials for this study. The former has been widely studied with much data available in the literature for comparison, while the latter has recently attracted attention as it can be synthesized from renewable saccharidic sources.…”

Incorporation of facilitating agents is one of the promising strategies being researched in recent years to cross the Robeson bounds for gas separations using polymeric membranes. The ways in which such inclusions modify the performance of membranes are not always clear. Here, we study the performance of two glassy membranes, Polyfurfuryl alcohol and Polysulfone, in O 2 /N 2 and CO 2 /N 2 separations, with Cobalt phthalocyanine in insoluble and solubilized forms as the facilitating agent. The results show that in general, three effects are important: (1) a barrier effect, (2) a facilitation effect, and (3) morphological effects on the polymer matrix due to an incompatibility between the particles and the polymer. These results provide some insight into the action of facilitating agents in soluble and insoluble form, when used as membrane additives.

“…When the peak shifts to a lower wavenumber it means that the IDA group is chelated with metal ions. 17,18 This finding suggests that small amounts of Zn 2þ added can totally displace Cd 2þ due to the passivation effect. 19 Comparatively, the resident of Zn 2þ would be chelated with the IDA group as excess of Zn 2þ is added.…”

“…GMA was reacted with IDA to produce the monomer (2-methylacrylic acid 3-(bis-carboxymethylamino)-2-hydroxy-propyl ester) (GMA-IDA) according to previous reports. 17,18 Subsequently, MA (0.237 M), MMA (0.237 M) and GMA-IDA (0.09 M) were added to the reaction flask, followed by potassium sulfate (K 2 S 2 O 8 , Aldrich Co.) as a polymerization initiator, yielding poly(MA-co-MMA-co-GMA-IDA) microspheres in latex form.…”

Highly luminescent hybrid CdS (diameter ¼ 3-6 nm)/copolymer nanocomposites are prepared by using the soap-free emulsion polymerization with chemical precipitation methods in this investigation. The core/shell type of ZnS/CdS nanoparticle on the shell layer of the copolymer microsphere can be obtained via the ion-exchange method. The luminescent intensity and energy of the hybrid CdS/copolymer nanocomposite not only can be improved by increasing the pH value due to the surface passivated by the iminodiacetic acid sodium salt of the polymer side chain, but also can be enhanced by the higher band gap inorganic materials ZnS shell layer. In addition, the CdS nanoparticle passivated by inorganic shell ZnS is more robust than when organically passivation. Furthermore, these hybrid nanoparticles are easily employed to manufacture the transparent copolymer membrane at the film formation temperature (608C), and they still keep their high luminescent property.

“…Gas carrier or facilitated transport membranes are known to reversibly bind the specific permeate of oxygen (Shentu and Nishide, 2003). Metal carrier complexes such as silver (Ag + ) (Hsiue and Yang, 1996), copper (Cu + ) (Lee et al, 2012) for olefins and CO 2 separation, and iron (Fe(II)) for carbon monoxide, manganese (Mn(II)), chromium (Cr(III)), and cobalt (Co) in membranes have been reported to facilitated gaseous transformation (Wang et al, 2002). Nishide et al and other authors have reported that the cobaltprophyrin (CoP) membrane is effective for oxygen facilitated transport.…”
